<P>PROBLEM TO BE SOLVED: To suppress the fluctuation of output power from an internal combustion engine or a torque shock at a drive shaft. <P>SOLUTION: In this hybrid vehicle, at a cylinder resting-side switching time when the operation state of an engine is switched from all cylinder operation to cylinder resting operation, partial cylinders of the engine are rested (S490) when a prescribed time tref1 elapses after a temporary increase of a throttle opening of a throttle valve is started by setting a positive opening correction value ΔTH (S430), and the engine 22 and motors MG1, MG2 are controlled (S500, S560-S580) so that torque based on required torque Tr* is output to a ring gear shaft 32a as the drive shaft while suppressing the lowering of direct torque at that time by torque from the motor MG2. <P>COPYRIGHT: (C)2011,JPO&INPIT |
